Most REEs are not as rare as the group's name suggests. They were named "rare-earth elements" because most were identified during the 18th and 19th centuries as "earths" (originally defined as materials that could not be changed further by heat) and in comparison to other "earths," such as lime or magnesia, they were relatively rare.
